Alertus App The Alertus App is our primary channel to inform students and employees of high priority, active threats on campus that have the potential to affect their immediate safety (such as secure and hold or urgent evacuation). In an emergency, we will communicate through as many channels as possible, including: Alertus App Alertus beacon Alertus desktop notification Lockdown External Audible Alarm (LEAA) Social Media Campus Status Alert on durhamcollege.ca DC email Digital signage Public address system (PA) DC App If you hear or see any notifications, respond immediately and follow the directions of security. iOS Download the app Android Download the app Alertus instructions Alertus Beacon In certain areas of campus where it is determined public address announcements are not sufficient or in labs and areas where a computer is not readily available, an Alertus beacon device may be installed on a wall. When the beacon is activated, a lighting system will flash, a high-pitched alarm will sound, and messaging will appear in the text area. Lockdown External Audible Alarm (LEAA) LEAA has been installed at both the Oshawa and Whitby campuses to alert anyone outdoors on campus of a lockdown situation within the campus buildings. LEAA will only be activated to alert the community about an immediate, active threat and will only be audible outdoors on campus in areas such as the bus loop, parking lot, the Centre for Food (CFF) gardens at the Whitby Campus, etc. When you hear the alarm: Attempt to flee the campus if you are in immediate danger. Avoid entering the buildings, unless safe to do so, and then immediately follow lockdown guidelines. Play this video to hear how the LEAA sounds.
